7 Inning Pitching Minimum?

What does the 7 inning pitching minimum mean?
It definitely doesn't mean that Yahoo doesn't
utilize the stats anyway...THEY DO!
I'm currently losing points to a team with 3 INNINGS!
I have 10!
Yahoo credits this guy with a point for 0.00 era (3 inngs)
over my 3.50, and gives this guy another point for 0.00
whip and mines 0.36....I have 10 innings!
This is another stupid Yahoo Fantasy inconsistency!
